I am after a caricature/cartoonist for a youtube channel logo

I am creating a youtube channel with me and 3 other motorcycle friends. As a joke we referred to ourselves as the Wild Hogs (Tim Allen, John Travolta biker movie). However, we'd like to set up a youtube channel documenting our adventures and want to do our own thing. I'm after a silly/fun image of the 4 of us. We haven't set up a youtube channel yet, but we're thinking something on the lines of "Mid life bikers".

I have attached some examples of the sort thing I am thinking of. But with our faces for fun.

Please advise if my budget is unreasonable.
